Sorry to say, I don't understand the question. I don't understand "live tab".
Firefox should just open the static local page. Shouldn't take more than a
second or two even when the system is bogged.

Will consider that, thanks. It would imply two bugs. The first causing
firefox to crash. Failure to open the specified page at startup would

I need to make a habit of starting it from a terminal until this is solved.
Otherwise will miss the incident too often.

To my knowledge the only thing running on an unpowered PC is the clock.
Some exotic machines might be able to run the BIOS or a Forth
PROM from the backup battery or cell. I don't know about that.
On most machines, no process survives a cold reboot. If that appeared
to happen, the process number must have been saved in a non-volatile store
and applied to a new process after the reboot. Seems perverse.
Firefox now has too much automation and it's causing trouble. We
need a way to disable some of this paraphernalia. Or a simpler browser.
Can the automatic search capability of the URL bar be disabled?
Other ideas?
Thanks, ... Peter E.

We're having trouble getting your pages back" means exactly that Firefox believes it crashed or failed to recover successfully from a crash, AFAIK, in which case it tries to restore the state of the browser at crash time (and does not load the user's home page, local or not, as if it hadn't crashed and was starting up normally). I've read that setting "Clear history when Firefox closes" is one way to obviate the problem (you might not want to lose your history, though). Another is to set "browser.sessionstore.max_resumed_crashes" to false in 'about:config'. I guess we can assume safely that you're closing your browser sessions "normally." Good luck.

Losing the history wouldn't be so bad but I don't see how firefox would
have a chance to clear history when crashing.

The default value is 1. Changing it to 0 seems reasonable.

I close each tab with a click on the x symbol.

AIUI, the "correct" behaviour when starting FF is a Home Page (your
choice), a blank page (mine), or the situation that pertained when you
last closed down (perhaps Cindy's choice). This last might involve
?hundreds of Tabs judging by Cindy's posts in the past.

I run two instances of FF, one as me (for banking etc) and one as
another user (for browsing). I just checked out clean shutdowns
and restarts with my own instance of FF and it's all OK.
As for my browsing, I always crash it at close down, either by
terminating X (Ctrl-Alt-Backspace) or by sudo /root/shutdown.
The effect of either is the same: FF started with "firefox" produces
a single Tab saying "Sorry. We're having trouble getting your pages
back" as you reported. Pressing Return (or clicking the button)
restores (inactively) all the Tabs that were present in the last
session: just what I want. (I don't want to have to dig them all out
of the browser History.)

Not running a DE, I always start it from a little xterm that's there
for just that purpose and for receiving any error messages. The jessie
version of FF spewed errors constantly, but stretch is much quieter.
I have a load of bash functions for suchlike, eg:
$ my-aptitude-doc-on-flashfirefox
$ my-deblis-on-flashfirefox
$ my-forecast-on-flashfirefox
$ my-hotmail-on-flashfirefox
$ my-python-doc-on-flashfirefox
$ my-radar-on-flashfirefox
$ my-weather-on-flashfirefox
and the effect of these is to produce two Tabs, the one requested here
and the one with "Sorry. …". (Any of the bash functions will take a
URL argument that overrides the default address.

It's possible to set up the system so that it restarts all the
sessions automatically when you reboot. I think one calls it a
"kiosk" system, and I remember someone on this list wanting to
set one up. The process numbers aren't saved. If they are, it's
likely a suspend/hibernation has been misdiagnosed.

It's a compromise. The more paraphernalia you cut out, the more pages
that will not work. Does the behaviour reported in your OP cause you
*great* concern? There is a button with a little house on it if you
specially want your Home Page (available at any time).
As you can read here, I'm perfectly happy with the behaviour described.¹
> Can the automatic search capability of the URL bar be disabled?
> Other ideas?
Sure: Edit→Preferences→Search→Provide search suggestions.
This *might* only stop locally generated suggestions. To stop, say,
Google from suggesting as well, you might have to set an option
on Google's search page. ("Other search engines are available.")
You might find other options in Edit→Preferences that can give
you a "simpler" browsing experience.
¹ I tried Opera on a slow laptop as it's reported to be faster.
It was, in normal use. However, when you started it the next day,
it would try and restore all the active Tabs as soon as you
started it, which was a disaster. I'd sit there waiting for the
weather forecast to appear while, say, 20 Tabs from yesterday
were clogging it up.
OTOH, FF only restores each Tab when you actually switch to it,
so my-forecast-on-flashfirefox gives me what I want immediately.
Cheers,
David.

Interesting. Thanks. For banking & etc. you have a dedicated user id
and login?
Drifting off the subject, but the banking I use invokes javascript. I
would have thought that unnecessary. Should be possible to accomplish
the results with processing on the server and HTML5 on the client.
Technology bloat?
> I just checked out clean shutdowns and restarts with my own

OK, thanks. The complaint at firefox startup here is probably only
following a crash of firefox. Curt's suggestion to set
browser.sessionstore.max_resumed_crashes to 0 seems appropriate.
> Does the behaviour reported in your OP cause you *great* concern?
No. Just wastes time. Opening a simple local HTML home page requires
roughly a minute rather than roughly a second.
> I tried Opera on a slow laptop ...
Thanks for mentioning that.

It has been my experience that the more IMPORTANT a web site is (government, bank, insurance, etc.), the WORSE it is. Eventually I got to the point where I simply GAVE UP trying to use any important web sites under Firefox + NoScript. Even if I allowed all the dozens of foreign Javascript domains that each web page relied on, it would still fail due to <https://noscript.net/abe/> violations. Your dream of a banking site that uses competent, non-broken web technology is going to have to remain a dream, I'm afraid.

Unfortunately :(. I use different Firefox profiles for banking to improve isolation, so at least they won't be attacked by a retailers tab.

At some point I will need to dive into documentation to see if the design is to isolate the containers sufficiently for me. Even if it is, I'm still concerned about a bug allowing container escape or information bleeding. Should containers not be sufficient for me, they still look like a significant improvement for those less tech minded. I currently run different browser instances for different tasks I want to isolate. For instance, I have a profile for one mastodon account and another for the other mastodon account. My bank gets its own profile, as do my utilities. Each of those is setup with uMatrix to disallow cookies and JavaScript not necessary for the particular site to work. I have over 50 profiles. Only two are allowed flash player and except for work requirements, I haven't used flash in a long time. Some profiles are inside containers. For generic shopping I have an instance that is more lax on cookies and JavaScript. My initial use of containers is for that. I would like to have a container per retailer ( or account required site ) that isolates each site and where all information about the site is wiped when the container is stopped/reset. Banks and social media will certainly continue having their own profiles, but a third of my profiles could move to containers ( if I start to trust them ). As to experiments, I need to see if I can get tools like lightbeam to help me audit isolation. I'll also passively test by checking for bleedover from different sessions. I want to see if I can enable and disable add ons per container. I presume not, but that would be a useful feature. ciao, der.hans >> Looks interesting.

My view is that it's easy to test whether unix permissions are working as the walls are on the local host. But to test whether there's leakage between containers, you have to either be at the other end of the connection or be monitoring all the traffic going out from the local host. > I currently run different browser instances for different tasks I want to > isolate.

It really needs inspection inside the browser and auditing via multi-site testing. But, $spouse isn't going to set up a bunch of different browser profiles. If containers would be viable for that use case, then they could be an improvement if the promise turns out to be at least mostly true. They would also be an improvement for my generic browser use cases. >> I currently run different browser instances for different tasks I want to >> isolate. > > I'm not sure how to stop different browser commands jumping into an > existing browser instance.

Yes. Usually I start a browser with a bash function as posted
earlier. Sometimes I use a bash function to open a Tab, even
where I could have done it with a corresponding bookmark.
But sometimes I'd start FF by pressing Return on an HTML in mc.
However, for a long time I've closed that off by having mc call
up lynx with localhost or w3m with -dump. Similarly, mutt only
uses lynx in the same manner.
But when I had used FF in such situations, the page always found a
running instance of FF (appropriate to the user concerned).

If I'm understanding you, I think this came up here recently: the
links /etc/alternatives/{gnome-,x-,}www-browser should point to
the appropriate binary.

You're very public-spirited.
Cheers,
David.

I ignore those and create my own. It looks like it's just a label with options for specific color and icon.

Thanks. For banking & etc. you have a dedicated user id > and login? The other way round: I bank as me, and browse as user "flash", hence $ my-deblis-on-flashfirefox which looks after changing user and allowing flash to display on the X display. (It also checks that I don't try to run a browser if I'm not using the most recent Debian version on that particular host.) Thus, my own files are inaccessible by the flash browser. > Drifting off the subject, but the banking I use invokes javascript. I > would have thought that unnecessary.

Banks, like everyone else, seem to feel the need to indulge their graphics fantasies on their websites. I guess it's pandering to the smart phone generation. Speaking of which, I guess we're lucky to still have Internet banking on computers; so much is now aimed at mobiles.

The fix, for me, was /etc/hosts: http://someonewhocares.org/hosts/ The only downside (which I don't understand) is that # scp -p <TAB><TAB> threatens to list ~14000 filename completions (IOW every hostname in /etc/hosts), but *only* as root. Cheers, David.

A mobile site can be accessible to firefox on a desktop and can be
more efficient than the desktop site. Eg.
https://www.envisionfinancial.ca/m/
vs.
https://www.envisionfinancial.ca/Personal/
Can debian imitate a mobile system to a server?
Thanks, ... Peter E.

It's possible to modify the User-Agent header string in Firefox and pose as a mobile browser (not necessarily an infallible maneuver). https://addons.mozilla.org/en-US/firefox/addon/uaswitcher/ > Thanks, ...

(I looked at the URL above and see the addon, but didn't want to install it -- I didn't see any example header strings.)
